Motorcycle safety-release back rest

ABSTRACT

Ordinarily uncovered vehicles on which the driver is at least substantially exposed and unenclosed, such as motorcycles and their likes and equivalents, are provided with a safety-release back rest rig that is comprised of and contains a vest-like garment for the driver to wear, which body-retaining garment is strapped ahead of the driver in sling-like fashion to the vehicle structure so as to provide secure and comfortable, lean-back support for the drive during running of the vehicle while at the same time being automatically disengageable from the vehicle structure when the driver dismounts and/or has at least a portion of his or her weight removed or uplifted from and/or off the seat for mounting the driver on the vehicle.

BACKGROUND OF THE INVENTION

When motorcycles and the like or equivalent unenclosed vehicles are being driven, there is unavoidably a considerable amount of vexatious, disturbing and disrupting wind pressure and turbulence action with which the driver must contend. This is oftentimes distracting and non-conductive to most careful and attentive operation of the vehicle. And, it is a condition that exists more or less independently, i.e., above and beyond particularly-encountered, naturally-occurring, ambient wind conditions. Of course, all of this is in relatively increasing or decreasing relationship (as the case may be) to the speed or forward velocity at which the vehicle is being driven as well as the general direction of existant wind (with respect to direction of vehicle travel).

Wind effects and the factors thereby generated aggrevate the typical lack of back and shoulder support problems and physical discomfort frequently, and often troublesomely, experienced by the unenclosed vehicle rider; being pronouncedly so in connection with motorcycling.

In this connection, even the inclusion and application of windshields on unenclosed vehicles does not entirely solve nor completely alleviate the problem. These are fine to thwart impact by insects, flying gravel, stones, and other particles. They are nonetheless incapable of eliminating or overcoming the mentioned wind factors and unsupported body aggrevations. The driver of a windshield-equipped motorcycle or the like still has to maintain some rather tight and strained body postures and steering control holding on operation of such conventionally-outfitted vehicles.

There have been heretofore proposed certain types of back-rest arrangements for motorcycles and the like. These, invariably, are of the constructions that offer support merely from the underside and/or from the rear of the rider.

Nonetheless, nothing in prior art appears to realistically concern itself with nor teach or lead to an effective, efficient and extremely comfortable and practical somewhat "sling-type", as it were, motorcycle or the like safety-release back rest contrivance or implementation in the manner of design and beneficial functionality and operability in the way so crucially indigenous as in the present contribution to the art.

FIELD AND PURVIEW OF THE INVENTION

The present invention, and the principal aims and objectives attainable in its practice, pertains(s) and direct(s) to a novel and, in the overall, unprecedented safety-release back rest rig or implementation in cooperative combination of the essential parts, elements and components therefor and thereof that effectuates:

(i) maximized positive and discomfort-avoiding or -preventing back and shoulder support and rider comfort for and during traveling operation of the vehicle by the driver thereof whereby the same is all afforded by a more or less sling-type holding arrangement of and for the driver; and

(ii) utmost convenience and safety in speedy and sure disengagement of the support rig from firm vehicle attachment at the will and wish of the driver and/or in the event of unexpected accident or other rider-throwing influence that may arise in use of or travel with the vehicle.

The achievement and provison of all indicated, with even more and additionally other benefits and advantages derivable in and from present practice appear and become more evident in the ensuing description and specification.

SUMMARY OF THE INVENTION

The present invention, in its genesis and as derives from the discovery on which it is based, pertains to an unprecedented and highly advantageous safety-release back rest rig assembly for a motocycle having forward or stem and rearward stern terminations and like or equivalent vehicle(s) comprising, in cooperative interrelated association and combination: a basic vehicle body structure; means on said vehicle body structure for seating a driver of said vehicle in appropriately mounted driving disposition on and for said vehicle; vest-like and equivalent garment apparel means for wearing by said driver, said vest-like means being adapted to well receive and encasingly hold said driver; at least a single safety strap means attachable and securable at or about its rearwardly-extending end in sling-like, forwardly-disposable fashion to the frontal part of said vest-like means for wearing by said driver; a safety strap(s) means holding and releasing component unit secured fixedly on said body structure of the motorcycle forward of said seating means for said driver, which component upon and by electrical energization thereof is adapted to receive, anchor and lockingly-engage the forwardly-disposable portion at or near its forward end of each of said therein plugged-in safety strap(s) means when said component is in a "locking" and safety strap-retaining position and to also release and freely disconnect, disanchor and disengage said forwardly-disposable end of each of said safety strap(s) means when said component is in an "open" and safety strap-releasing position; an electrical switch and circuitry switching unit under said seating responsive for "on" and "off" setting purposes to applied driver weight when one is sitting thereupon and electrically connected with said component unit which is adapted to pass adequate electrical energy by means of interconnecting electrical circuitry so as to cause said component unit in said cooperative rig combination assembly to firmly and strongly anchor, engage and lock to close and secure any portion of said forwardly-disposable end(s) of any and all of said safety strap(s) means therein plugged when at least a predetermined portion, if not all, of the total supported weight of said driver is mounted and disposed and resting upon said seating means; and, conversely to cause said component unit to quickly, freely and easily disanchor, disengage and open to free and unsecured liberated disposition any portion of said forwardly-disposable end(s) of any and all of said safety strap(s) means therein plugged when more than said predetermined portion, if not all, of the total supported weight of said driver is dismounted and neither disposed nor resting upon said seating means.

Still other features and implementations of beneficial import and salience are advantageously combinable in and made integral part(s) of the basic, more-or-less "harness" sort of above-delineated safety-release back-rest rig assembly of the invention.

Thus, various suitable parts, elements, sub-assemblies and overall assemblies plus other equippage for utilization, as well as working details, embodimental instructions and parameters and other specifies of the invention are also set forth in the following Specification.

Motorcycles,                           per se, normally have two, but sometimes more,                                 wheels. The basic and fundamental wheel pair is                                attached to or depend from in spaced, aligned rela-                            tionship, a frame. Upon the frame is situate a                                 seat for the rider or cyclist (with often enough                               room thereon for a rearwardly mounted passenger                                behind the rider). The vehicle is generally steered                            or directed in movement by at least a single                                   handlebar steering arrangement (usually a trans-                               verse but at least effective pair of same to be                                held and gripped by both hands of the cyclist).                                Connected to the handlebar, or an actual part                                  of it, is a neck portion or extension. The neck                                leads to an associated fork to turn the (usually)                              front wheel for steering and movement guidance.                                Motorcycles (or more simply and popularly, "bikes"                             as they are sometimes described in the vernacular)                             can include 3-wheel versions. These include those                              wherein the third wheel provides support for a side                            car. For present purposes, meanings and comprehen-                             sive intents, equivalents of motorcycles include                               foot-pedalled bicycles, tricycles and other similar                            vehicles. Thus, they may be such vehicles as the                               so-called "Mo-Peds" and the like, which are motor                              assisted or driving, power supplemented through cir-                           cumferential drive-connected wheel-                                            engaging locomotion assemblies or even other                                   auxiliary motor means for added locomotive assist-                             ance. Or, they can also be the more simple, con-                               ventional motorbikes (which, in effect and result,                             are much lighter and lower powered versions                                    of motorcycles). Additional to those and intended                              to be construed as "motorcycles" within the meaning                            of vehicles adapted to be benefitted by practice                               of the invention are such vehicular products as the                            so-called "snowmobiles", certain types of power or                             other boats and so forth.                                               25     General designation of the releasing component                                 to disengage the holding strap or the like which                               hooks to vest back rest and the like designated by                             Ref. No. 69 and below more fully described but as                              portrayed in FIGS. 1, 9 and 10 of the Drawing.                                 Many varied designs and embodiments may be con-                                ceived and provided to serve as efficient, electrically-                       controlled releasing units or components. In all,                              however (and regardless of particular hookup                                   features and connecting arrangements), the function                            is to "open" or unlock the component so as to free                             or clear the strap clasp engagable (or engaged) by                             catch means in the releasable component when the                               component is activated by changing to an "off" or                              other component opening setting of a pressure-                                 sensitive or equivalent sort of actuating switch                               associated with the seat. The switch is normally                               turned "off" so as to open or "break" the re-                                  leasing component activating circuit; this being                               secured due to achievement of a switch "on" by                                 means and virtue of the seat-depressing weight of                              rider when mounting and sitting, resting or riding,                            upon the seat. This then puts or keeps the re-                                 leasable component in the "closed" or strap-                                   engaging or -holding position. It (i.e., the                                   component) goes "off" when all or any                                          desired and pre-determinable portion of the rider's                            weight is relieved from the seat (say 50-100                                   lbs. or so depending on how any given set-up                                   is wanted to be operative); to thus electrically                               activate the strap-releasing component into the                                "open" position. The opposite effect giving                                    identical results can be achieved if desired; this,                            in other words, being to have the seat switch                                  turned "off" by rider weight pressure so as                                    to electrically activate the releasable components                             into its strap-catching "closed" or "shut"                                     position position turned "on" to de-energize the re-                           leasing unit control system circuit putting it into                            the "open" and strap-releasing position                                        when there is release or relief of rider-weight                                influence pressure off of or up from the seat.                                 One convenient arrangement and constructioned                                  form for the releasable unit is to utilize a strap-                            engaging pin or catch that is movable and thrown                               or controlled to respective "open" and "closed"                                position (or vice-versa) by a solenoid system which                            is such as to make the pin movable in one or two                               directions upon electrical energization; this                                  being so electrically-connected to the seat switch                             as, regardless of any given circuitry and energi-                              zation details, to render the releasing com-                                   ponent in "closed" setting when the rider is                                   on the seat but otherwise "open" when the                                      rider is not on the seat (or not exerting or                                   putting enough desired weight on the seat if less                              than full weight for switch control). As is well                               known, the effect of the solenoid type unit is to react                        or function by magnetic-field creation when electrically                       charged or supplied, thus forcing movement in one or                           another direction of a magnetically-responsive element                         or unit therein subject to attraction or repulsion by                          the magnetic unit.

This strap or band in most cases is necessarily                        to be at least essentially, if not completely, non-elastic                     or not-substantially-stretchable material such as                              leather, pliable (but without appreciable "give"                               on normal attempts to stretch or elongate) plastic,                            tough-knitted or otherwise constructed belting stock                           of textile of metallic strands, flexible and for                               practical purposes non-extensible metal and so forth.                   28f    Fastener connection (shown only in FIG. 12) for                                rigidly securing one end of the strap to a side of                             the seat at and from which fixed point is commenced                            the seat incirclement of the strap, such as the                                nut, washer and bolt set going through an accommo-                             dating hole (not shown), preferably reinforced,                                provided in the seat strap at or near its fastened                             end. Other fastening arrangements can also be                                  employed, such as riveting, stitching, gluing,                                 welding (where appropriate), etc.                                       29     Spiral expansion spring or equivalent expansion                                yielding means to connect free end of strap to                                 seat switch operating button, knob or other switch                             "turning" projection. While very useful, such                                  spring means are not absolutely critical or nec-                               essary. In any event, the idea is to have the                                  weight of the rider on the seat (or some portion                               thereof) tend to stretch the strap enough to turn                              the switch "on" when the seated position is taken and                          to turn it "off" when there is a release or taking                             off of such weight.

Although not usually desirable                            for reasons of non-adjustability as below-explained,                           the other end of the strap fastenable to the vest                              69 may also be so arranged.                                             52     Housing enclosure or equivalent as cover box structure                         for releasing component unit.                                           53     Clamping holes in releasing unit to allow easy and                             convenient handlebar-top mounting and affixing                                 arrangement of releasing unit permitting passage                               therethough of suitable connectors; such as a                           54     U-clamp (or equivalent fastening means) as depicted                            in FIG. 6); with accompanying                                           54w    Nut and washer parts to tighten the U-clamp to                                 strongly and securely hold in place the releasing                              unit.                                                                   55     The solenoid-activating (or equivalent) actuator                               for getting the releasing unit into "open" or                                  clear and free or "closed" or locked or shut posi-                             tion with respectance for engagement of safety-                                strap 50 therein. This, as shown only in FIG.                                  3, can advantageously be one of the above-described                            "CEL-NOID" or like units.                                               56     Shaft from actuator to the actual "hold pin"                                   which engages and locks the safety-strap.                               57     Rubber or equivalent stop (not absolutely nec-                                 essary) on shaft 57 or its extension 58 to                                     serve as stop-motion device in retraction of                                   "hold pin" into the housing enclosure 52 when                                  the releasing unit is actuated into the "open"                                 and safety-strap-releasing position.                                    58     Extension (when necessary) of shaft 56 to juncture                             with "hold pin" part. In this, the shaft 56 and                                any extension 58 of same are usually cylindrical                               and of smaller diameter than the "hold pin".                                   However, they can, if desired, be the same as the                              "hold pin" so that the latter, in effect, is merely                            the terminal end part of the shaft (or extension                               thereof). Of course, the shaft can also be of                                  larger size than the "hold pin", although this                                 is normally not done excepting when, for some                                  particular reason, a very small-sized "hold pin"                               is wanted. Likewise, other than cylindrically-                                 configured shaft(s) and/or "hold pins" can be                                  utilized.                                                               59     Bidirectional arrow (included in FIGS. 3, 7                                    and 8) indicating "hold pin" back-and-forth                                    motion to put the releasing unit into the "open"                               position when the pin is retracted and in the                                  "closed" or safety-strap-locking position when                                 the pin is outwardly extended. In the usual set-                               up, a shaft "throw" or movement span of 11/4" (±50%                         or so) is adequate.                                                     60     The "hold pin" or catch for engaging and locking                               the free-end of the safety strap when the releasing                            unit is in "closed" or shut and locked position.                               The hold pin usually goes through an accommodating                             ring or equivalent buckle or clamp attachment at                               the free end of the safety strap when the latter                               is inserted into the releasing unit for locked                                 engagement therein. Although such rings are here-                              inafter illustrated in connection with the strap                               50, it is evident that they may be replaced by                                 reinforced-apertures in the free-end of the strap                              and/or grommets or grommet-like fixtures built                                 into the free end of the strap. Likewise, while                                the safety-strap-catching arrangement is primarily                             herein illustrated by the ring-traversing "hold                                pin" sort of assembly above explained, it is to                                be understood (although not illustrated in the                                 Drawing) that this sort of combination may be                                  replaced by equivalent sorts of locking and grasp-                             ing devices and constructions for keeping the safety-                          strap in engagement with the releasing unit when                               it is intended to be therein fixedly held and locked.                          Thus, the free end of the safety strap may be pro-                             vided with an "alligator" or toothed (or other) pro-                           jection terminal attachment which fits into accommo-                           dating jaw-like retainers or indentured clamps for                             keeping, when so wanted, the safety strap locked in                            place. Likewise, it is also possible to utilize                                strong magnet holding means that are adapted to                                go "on" and "off" as the releasable unit is accord-                            ingly controlled and actuated which magnetically                               catch and grasp a magnetically-attractable and                                 securable end portion of the safety-strap.                              61     Support holes or openings, acting somewhat as                                  journal bearings, in the frame housing of the                                  releasable unit.                                                        62     A partially or fully enveloping bracket fixture                                (excepting for an unenclosed opening to admit and                              take out the connection for the safety strap hold                              pin when it is either retracted or extended).                           64     The accommodating ring or the like at the free                                 end of the safety strap which is caught and held                               by traverse therethrough of the "hold pin" when                                extended to have the releasable unit in "closed"                               or locking position.                                                    65     An auxiliary (and optional) "on-off" or reversing                              switch to keep power out of (or in - depending on                              which sort of solenoid actuating circuitry and                                 arrangement is employed) the "CEL-NOID" or                                     like or equivalent part of the releasable unit                                 so as to render the latter inoperable and keep                                 it open when switch 65 is not turned "on". This                                is a convenient addition to or supplementation of                              the assembly since it permits the cyclist to turn                              on or shut down the releasable unit so as to keep                              it "open" at will, as during actual driving travel                             of the motorcycle (or equivalent vehicle). In                                  this, the driver may not always want the apparatus                             working whenever he (or she) is sitting on the                                 seat; there being times as can readily be under-                               stood when the safety-release back rest appliance                              of the present invention may be only wanted or                                 needed to be utilized during certain intervals                                 or portion of any involved trip or travel with                                 the motorcycle.                                                         69     General identification of back-rest vest or equiv-                             alent jacket, coat or other vestment or garment                                (or even a simpler mid-section encompassing                                    cincture or girdle-like affair). The vest                                      depicted in FIGS. 1, 9 and 10 of the Drawing                                   is shown as a sleeveless garment of typical vest-                              like style. Those are often desirable to make                                  of heavy denim or the like cloth or fabric.                                    However, cold or foul weather jackets and the                                  like gear (with full sleeves, etc.) can be                                     used instead of the less cumbersome vest, as                                   may coats or other types and styles of apparel.                         70     Vest arm holes.                                                         71     Reinforced stitched-on or otherwised securely-                                 affixed support strap for back of vest (shown                                  only in FIG. 10). While such extra construction                                is optional, it definitely tends to make for firmer                            and more sturdy support characteristics in and                                 capabilities of the back-rest vest (or the like                                or equivalent garment). It is thus usually                                     desirable to have incorporated in the vest.                             75     Affixed belt or strap connection from (and                                     usually at the sides and in furtherance of                                     reinforcing support 71) the vest to the free                                   ends of which suitable means such as connecting                                rings, loops or other fastening means are provided.                            When a single safety strap is employed in extension                            from the releasable unit, it is connected with both                            of the vest straps so as to terminate at about the                             rider's frontal mid-section. When double safety                                strap arrangements are utilized, each of the                                   separate safety straps are respectively connected                              to each of the integrally dependent and loosely-                               hanging vest belt or strap connections so as to                                secure the rider in a more or less sling-like                                  arrangement.                                                            76     Connecting rings or the like engageable fixtures                               at the ends of the vest straps to and/or through                               which the safety strap(s) from the releasing                                   component or unit is/are attached.                                      80     An adjustable buckle (shown in more or less detail                             in FIGS. 3 and 13-15 of the Drawing) to make                                   a nicely and comfortably taught lengthening or                                 shortening of the safety strap to adjust to                                    particular vest or the like designs and rider's                                posture and desired positioning on the seat. While                             a given-length safety strap may be employed, the                               inflexibility of same does not always provide for                              most comfortable and optimum usage of the back-                                rest assembly. It may be too long for some                                     drivers and desired posture situations and                                     too short for others. An adjustable buckle                                     arrangement generally overcomes any such sort of                               deficiency.

With an overview of the several depictions, views and illustrations of the Drawing being maintained (especially in light of the foregoing explanatory parts, etc., elucidations), the subsequent portion of this Specification now turns to a somewhat more cohesive and particularized disclosure and exposure of and coordinated amplification upon the invention; including therein most appropriate and expedient (or best) manners and means stemming from the foregoing in which the same may be advantageously and propitiously embodied and practiced.

In this connection, the basic principles and limitations of: motorcycles; motorcycle seats; solenoid-powered and like or equivalent actuators; electrically-operated door and other article or item locking and/or clamping mechanisms; pressure and otherwise actuated and like or equivalent electric switch or circuit opening and closing devices; power supplies; fastening means; straps and belting and banding; clamping and hooking devices and contrivances for strap(s), rope and the like; and buckling and clasping (adjustable or otherwise) contraptions and implementations for strapping, belting, cordage and rope and so forth are so widely comprehended by those skilled in the art that greatly detailed elaboration of all the basics thereof is not herein made or attempted; the same being unnecessary for thorough understanding and recognition of the advance possibilitated for achievement and realization by and with the development in and of a motorcycle safety-release back rest and the like improvement that is according to and in keeping with the present invention.

PARTICULARIZED OPERATION AND USE DESCRIPTION OF THE INVENTION

As is clearly evident and readily-enough apparent in and not-difficultly deducible from the foregoing disclosure and description, the present invention in basic essence and substance contemplates a vest or other like or equivalent jacket or coat-type of vestment or garment that is wearable by the driver of a motorcycle (or like or equivalent vehicle as above contemplated and indicated) which, when assumed and worn by the driver, is optionally attached or "hooked-up" via safety strap or belt connections first made at the vest to be then "anchored" or locked to a forwardly-disposed holding or locking releasable component or unit to which the opposite end of the safety strap is secured when the assembly combination is fully connected and in operable function.

The locking elements or "anchors" at the point of safety strap securement to the releasing component or unit are so fixed that they unlock and release quickly and easily for complete disengagement when the cyclist, purposely or involuntarily, moves off or is lifted or thrown upwardly from the seat, (or like or equivalent driver support means in other than motorcycle vehicles). This automatic disengagement, especially in cases of unexpect disruptions and/or accidents, frees the cyclist (or driver or rider of other vehicle or like or equivalent locomoted transport equipment) from unescapable fixed and dangerously bound conection and association with an onward moving vehicle; thus tending to greatly minimize if not entirely escape more serious physical injury or even lethal trauma than if freedom from the vehicle attachment could not be so readily provided and obtained.

At the same time, when the safety-release back rest appliance or apparatus combination of the invention is will-fully utilized and put in effectively-functioning operability for its intended usage and purposes, the cyclist or (other vehicle driver) can quite comfortably and securely lean back during the ride in restful, more comfortable and safer (i.e., much less "nerve-wracking", strenous and/or tedious) posture position in the course of vehicle running and movement. This back-rest support, as has been mentioned, is ordinarily materially beneficial to vastly enhanced and much more relaxed ride enjoyment and comfort during the involved transportation. It greatly aids, as has been noted, in coping with the sheer wind velocity factor and influence in normal motorcycle and the like driving and riding.

Excepting when involuntarily caused and motivated by unintentional and/or unwanted accident or roughroad travel, the driver can readily release himself from attachment to the vehicle by simply getting off the seat. Or, as has been explained, he can purposely disengage and not utilize or take advantage of the unit by turning "off" of the optional hook up switch during travel. Any or all of this releases the safety strap from the locked engagement to the motorcycle or other vehicle. Also, especially when readily detachable couplings to the vest are employed (such as the illustrated snap hooks and the like catches or fastening clasps, the rider is also free to easily and completely disengage the strap from the vest, leaving him entirely unencumbered with unnecessary equippage and appendages.

Along this line and as been explained, it is generally more advantageous and desirable for the releasing-unit-actuating-seat switch to govern the unlocking of the strap when full rider weight is taken off the seat. However, as has also been mentioned, it is sometimes of preference or pre-determined choice to have such releasing motivation implemented when less than full driver weight is relieved from or taken off the seat. The seat switch can be readily designed and arranged to be so operative.

The mentioned 50-100 lb. or so weight-removal of or from (and upon) seat pressure in order to activate the seat switch is in the typical range when less than full rider weight removal provisions are wanted to work the seat switch. Naturally, other loading values to work the seat switch can also be adapted. Such reduced load actuating arrangements are frequently considered to be of advantage in order, especially in cases of accident, to not have the rider-uplifting action so violent or forceful as to cause him or her to be completely thrown off the seat in overcoming of involved full weight before effectuation of the desired safety-release action and mechanism.

In another possible and sometimes desired emodiment variation in practice of the invention, the releasing component or unit can be readily positioned as a unit assembly interconnected at the end or close thereto of the vest side of the safety strap or, for that matter, intermediate the length of the strap. While not previously discussed (and not shown or in any way depicted in the Drawing), this leaves the possibility of having the safety strap securely and dismountably fixed to the handlebar, neck or other portion of the vehicle (although it can also be thereat disengageable in such arrangements).

With such manner of arrangement, the releasing unit can then be easily and analogously disengaged from the vest when purposeful dismount or accidental throwoff from the seat is done or encountered by the rider.

In fact, as a further sophistication of such variation, a vest-side oriented or intermediate-of-safety strap disposition of the releasing unit can be equipped with an extra single or double set of quick-opening coupling connections (above and beyond the automatic unlocking disengagement mechanism) for achievement of entire flexibility in handling and use of a so-arranged releasing component.

Yet another refinement that can be included in incorporations of the present invention which, despite its lack of illustration in the Drawing is obviously and easily visualizable by and comprehensible from mere description thereof, is to have or make the safety strap(s) so arranged and storable when not extending in self-withdrawing, automatic recoil containers or structures, much in the manner of automatically retractable "measuring tape" and "wire- and/or -cable" dispensing and retracting devices. The generally spring-actuated recoil systems for the safety strap(s) can be of the entirely automatic variety which self-withdraw when no or insufficiently extending force or pull is thereon applied or in the style of those that require actuation of a button or other generally manually operated retracting-motion-starting means to effectuate the recoil mechanism. Such compementary arrangements avoid the bother and possible nuisance (or even danger) of having an uncoiled or unwrapped strap left free to dangle or fall about or upon the vehicle mechanism and/or the body of the rider involved when the strap is disengaged from full operative connection.

Somewhat along this line insofar as concerns neatness and compactness of embodiments of the invention, the releasable unit or component, no matter where positioned, is desirably as small and compact as possible. When handlebar mounted on a motorcycle, care should be taken that its placement does not hide or obscure the instrument panel.

A still further refinement of great advantage for complementary association with and additional inclusion in the safety-release back rest apparatus and combinations of the present invention (also not portrayed in the Drawing but fully understandable and visualizable from mere description thereof) is the incorporation of a "tether switch" or "kill button", as it were, supplement to and in the combination. These can well be the well known varieties and constructions commonly utilized in "snowmobiles" and like vehicles, and/or likes and equivalents thereof. A "tether switch" usually must be "on" in order for the vehicle to run or be capable of any operation. Its actuation (somewhat analogous to the setting off by the release or readying-for-explosion pin lifting or setting in a grenade or the like) requires very little force for the purpose. It is usually employed so as to be "on" when the driver has grasp of at least one of the handlebars or other steering means of the vehicle; but chain, cord or otherwise link-connected to the hand, wrist, elbow, belt loop or other vestment part of the driver, foot or wherever.

In this way, any excessive (and literally not very much at that) movement or displacement of the body part to which "tether switch" connection is made with the driver--indicating or caused by his disengaging manipulation for any reason with the operational devices necessary for good and orderly running of the vehicle--shuts everything off and immobilizes vehicular locomotion and running possibities (including stopping or instantaneous "killing" of motors and the like drive power sources).

The excellent and very practical and beneficial results achieved in practice of the present invention are obtained by the very propitions and functionally excellently adapted interrelationship and calculated, pre-conceived correlation of the seat switch actuating potential as regards its operation of the releasing component or unit and the latter's affecting of the back-rest vest (or the like) securement in holding place and position about the driver when his or her weight is on the seat; while at the same time entirely and with quick facility capable of disengaging and uncoupling all that when not enough driver weight is on the seat to push or urge the seat switch into safety strap locking and escape prevention release of the strap interconnection and engagement with the releasing unit.

While embodiments of the invention are well adapted to be installed on already-made motorcycles and the like or equivalent vehicles, it is plain and needless to mention that the presently-contemplated safety-release back rest arrangements are readily capable of being designed into and made integral appurtenant parts of newly-made, production-line or otherwise assembled new vehicles.

Many changes and modifications can readily be made in and adapted to embodiments and practices in accordance with the present invention without substantial departation from its apparent and intended spirit and scope, all in pursuance and accordance with the same as it is set forth and delineated in the hereto-appended claims.
